Besides the article from Andrus and Eric take a look at the one by Bill
Dudney.

There was also some talk on the Tapestry list but I couldn't find it
again.

I've used Hibernate before and found it quite good, but soon ran into
some roadblocks that drove me nuts. I can't remember the details but
found certain aspects to be less than intuitive and took a day or 2
overcoming a few issues. This was over a year ago so maybe it has
gotten better (as I have as well). I tryed Cayenne on a recent project
and had a lot of success, I wouldn't say it was all smooth sailing but
that was because I was learning it and Struts at the same time, and I
NEVER had the same trouble as I did with Hibernate. Thats just my
experience anyway.

I personally think Cayenne is a fantastic tool, when compared to other
tools
that I've used. Extremely easy to learn, easy to use, fast and reliable.
The
mailing list is fantastic, and the community is great.

I can't comment on Hibernate as I never used it. Though I know there is
a few more folks who have experience with both, so please help us out.

What I can say is that our community is actually an advantage over
Hibernate overgrown crowd. Requests are never left unanswered (or
answered with RTFM). Just look at the comments in this thread -
http://objectstyle.org/cayenne/lists/cayenne-user/2004/09/0089.html -
you'll see what I mean ;-) IMO Cayenne is currently in this "sweet
spot" of the community size with the best signal-to-noise ratio.

So basically your colleague overlooked a valuable resource - this
mailing list, or simply was too shy to ask. I am sure he'd be running
in no time if he'd asked for help.
